Consequences of Protein Misfolding

 Topic: Protein Folding and Molecular Chaperones - What happens when proteins fold incorrectly? Consequences of Protein Misfolding Vina Ong 20554965 Section: 126 Ares Rao A protein is made of amino acids that supply cells with their formation and execute most of their activities. Proteins can easily be denatured and refolded which happens spontaneously as the denaturing solvent is added and removed, under the proper circumstances. (Alberts, 2014) Since they can be easily denatured...

Protein Synthesis

living creatures, work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways, the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process, there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding, through four nitrogen bases (adenine...

Amino Acids Glycine is the smallest of the amino acids. It is ambivalent, meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH, glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent, meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins, only the L-isomer is found. Serine differs from alanine in that one of the methylenic...

protein structure

Protein structures Proteins are polymers of amino acids and are important in the formation of living organisms. Amino acids are made up from carbon, hydrogen, oxygen, nitrogen and sometimes sulphur. They have a two-carbon bond. One of the carbon's is part of a group called the carboxyl group. A carboxyl group is made up of one carbon (C) and two oxygen (O) atoms. That carboxyl group has a negative charge, since it is a carboxylic acid that has lost its hydrogen (H) atom. They also have an amino...

BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo, and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of amino acids. A series...

Proteins are made from about 50 to 2000 amino acid residues. Figure 1 Why purify proteins? They are many reasons why a biochemist might want to purify a protein. For example to...

Determination of an Unknown Amino Acid from Titration

of An Unknown Amino Acid From Titration Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96, and the pKa's found experimentally were 2.0, 4.0, and 9.85. The accepted pKa values were found to be 2.10, 4.07, and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid, hydrochloride...
